During the reign of her brother-husband, Jaehaerys I, Alysanne and Jaehaerys once visited Winterfell with six dragons. While at Winterfell, Alysanne grew bored and mounted Silverwing, flying further north to see the Wall. They stopped at the village Queenscrown on the way.[4][1]

At some point, Vermithor and Silverwing became a mated pair. During the Dance of the Dragons, Vermithor and Silverwing were said to often coil about one another in the fields.[5]

As the Hightower host remained at Tumbleton, so did Ulf with Silverwing. During this time, Silverwing was kept unchained beyond the town walls, free to fly and hunt. During the Second Battle of Tumbleton, an army of four thousand men strong, led by Addam Velaryon upon the dragon Seasmoke, surprised the Hightower host at Tumbleton with their night-time attack. Ulf slept through the battle, but even without a rider Silverwing took to the sky during the battle. At one point, a crossbowman shot a bolt at the dragon.[5] Silverwing avoided further battle and instead circled the battlefield for hours. She descended only again the next day, after the sun had gone down, and landed between the slain Vermithor, Seasmoke, and Tessarion. The singers claim that Silverwing attempted to lift Vermithor's wing on three occasions, but Archmaester Gyldayn considers this to most likely have been a fable. When the sun rose again, Silverwing began to fly listlessly across the field, where she few on the burned carcasses of men and animals.[5]

Silverwing's rider, Ulf the White, insisted he should become the new king of the Seven Kingdoms, as King Aegon II was missing, Prince Aemond dead, taking over the plan of the newly deceased Hugh Hammer, who had died in the Second Tumbleton as well. Silverwing became riderless when Ser Hobert Hightower, one of the Caltrops, gave Ulf the White poisoned wine. Lord Unwin Peake offered a thousand golden dragons to any knight of noble birth able to ride Silverwing. Out of the three men who came forth, the first had his arm torn off and the second burned to death. The third man then changed his mind.[5]

Silverwing was one of only four dragons still alive at the end of the Dance. Although accustomed to men, Silverwing became wild during the reign of Aegon III Targaryen, and eventually made her lair on an island in Red Lake in the northwest of the Reach.[6]
